Kubernetes as a standard development platform We started with single, often powerful, machines that hosted many applications. Soon after came virtualization, which didn’t actually change a lot from a development perspective but it did for the field of operations. So developers became mad, and that’s when the public cloud emerged to satisfy their needs instead […]
